Heinz Wolff has died he interviewed Paul on the N-Prize project an while back, but to a lot UK people will be remembered for The Great Egg Race which i think has inspired a lot of inventors and engineers into their professions over the years in this country and possibly around the world in places it was shown.

Also passing away recently (last month) was Lutz Kayser, founder of the first private space company OTRAG. We considered his design of using multiple sugar rockets to do the N-Prize with sugar. Even with his low cost design and reusing the rockets, just the cost of the solid sugar propellant would put us over budget.
